GATE.

SPECIFICATION forming part .0f Letters :Patent N0. 226,695, dated April 20, 1880.

Application filed February 27, 1880.

To all whom it 'may concern:

Be it known that I, GEORGE H. AYL- WOR-TH, of Brighton, in the county of Macoupin and State of Illinois, have invented a new and valuable Improvement in Gates; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings,making a part of this Specitication, and to the letters and figures of reference marked thereon.

Figurel of the drawings is a representation ot' a side view of my improved gate, and Fig. 2 is a top view thereof.

This invention has relation to means for opening and closing gates; and it consists, mainly, in the construction and novel arrangement, in connection with the gate-post, gate, and the operating-cords in line with the roadway, of a com poundV lever consisting of three sets ofpivoted bars forming three toggle-joints, which are pivoted together by theends ot their arms, and by their joint portions pivoted respectively to the gate, the gate-post,'and the operating-cord, as hereinafter shown and described.

In the accompanying drawings, the letter A designates any ordinary gate, and B the gatepost to which it is hinged. C C are the roadposts, having pulleys or bearings D for the operating-cords a.

To the top of the gate-post is attached la plate, b, or bearing, having a pivot pin, c, whereby the intermediate toggle-joint E is pivoted to the gate-post at its middle or joint portion, the ends of its bars extending' outward and backward away from the gate, as shown in the drawings.

To a bearing, d, on the gate is pivoted, at a, the jointed portion of the longer toggle-joint F, the ends of which also extend outward and backward to the ends of the intermediate toggle-joint E, and are pivoted thereto and to the ends of the rear or outer toggle-joint, G, by the pivots e. The latter toggle-joint is bent reversely at its joint, its bars extending forward,

so that when itis spread by pressure upon its joint portion g it will tend to spread the other two toggle-joints. The operating cords are pivoted to the joint portion of this outer toggle-joint, as indicated at It.

The gate being closed can be readily opened by pulling the cord on either side, which pulls the outer toggle-joint and elongates the compound lever, of which it forms a part, turning 5 5 the gate in the opposite direction and throwing it well away from the roadway. After passing through the gate it can be closed by pulling upon the opposite cord, which spreads the outer toggle-joint, G, and thereby spreads 6o the gate toggle-joint F and the fulcrum togglejoint E at the same time, thereby forcing the pivots c and n from each other and turning the gate into the closed position.

It will be observed that in this compound cords a a, of the three toggle joints E F G, piv- 8o oted by their joint portions respectively to the post, the gate, and the operating-cords, and by the ends of their arms together at ce, substantially as specified.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.

GEORGE H. AYLWORTH.
